Integrating rules of modular coordination to improve model authoring in BIM

As the adoption of Building Information Modelling (BIM) becomes pervasive and its level of application matures, the need to incorporate domain-specific knowledge in BIM authoring tools is also increasing. Rule-based scripts that assist and guide the modeller in model authoring are needed to enhance the level of usage of BIM. The authors developed a framework for incorporation of rule-driven domain knowledge into BIM authoring tools. With the objective of customizing the modelling process using a set of rules, the approach presented in this paper combines rules of modular coordination in prefabricated building with BIM. Modular coordination, a dimensional coordination system for sizing and placing building elements within a three-dimensional (3D) reference system, is translated into rules that are incorporated into the BIM authoring tool through object-level and process-level interventions. The study explores various options of parametric modelling for integration of identified modular coordination rules. The aim of integrating modular coordination rules is to assist the user during the modelling process. The proposed approach has the potential of reducing inconsistencies and time spent in modelling and documentation allowing the designer to spend more effort on value-adding design tasks. With the help of a case study and an experiment, capabilities of the proposed framework are demonstrated and validated.
